Stealth Kits from HIDS4U offer the very best in aftermarket Xenon HID Lighting. Compared to standard Halogen Bulbs, Xenon HID (High Intensity Discharge) gives a significantly brighter light output, with a stronger beam pattern to better illuminate road markings, signs & potential hazards to create a far safer road experience when travelling at night. Once you’ve upgraded to Xenon HID light, you’ll never want to go back to halogen!


These kits are developed by our in-house engineers, who work closely with the manufacturer to our exacting specifications. The Stealth ballasts are called so, as they use the latest digital technology to make the ballast unit much smaller than many other kits, making them incredibly easy to hide in your vehicle. If however they are on show, the brushed aluminium with braided cables will look at home in any engine bay.

Power Rating

You can choose whether you’d like 35W (*up to 300% more light) or 55W (*up to 400% more light) and with the majority of vehicles accepting either, the choice is yours! (*Than standard Halogen bulbs)


All our Stealth kits are CAN-Bus compatible, ensuring ‘Error-Free’ compatibility with virtually all vehicles, without the ‘blown-bulb’ dashboard warnings that can show with most older & cheaper kits. The ballasts also feature advanced EMF suppression to eliminate radio interference.

Plug & Play

These kits are designed to be 'Plug & Play', meaning no wiring to the vehicle's battery - simply connect to your existing headlight bulb connector. On average, a kit takes around 30 minutes to fit. However, if you have any doubts, this is a simple task for any auto electrician.

Colour Temperature

The kits come in a variety of colour temperatures to suit how you’d like your lights to look.

  • 5000K (White & Bright) - Pure white ‘daylight’, giving the most light output (Recommended)
  • 6000K (Blue Tint) - Blue tinted white light, giving a modern, cool, ice-white look.
  • 8000K (True Blue) - Intense blue, best for styling and an ultra-modern look.

Headlight Type

The type of headlight unit on your vehicle will determine whether you require Reflector or Projector Bulbs. It’s quite easy to check yourself.

  • Reflector - If you look into your headlight unit and can see the bulb, and see the back wall (reflector) of the headlight unit, then you have reflector style headlights and you should use our special anti-glare HID bulbs.
  • Projector - If however, you look into your headlight unit and see what looks like a lens or dome in front of the bulb, this will be the projector type lens. In this case, the projector lens focuses the light much more accurately, so the best option would be our normal (non-reflector) HID bulbs.

Why a Stealth Kit?

With plenty of cheap, inferior quality kits on the market, it’s important to remember that there can be vast differences in terms of performance & reliability from one kit to the next. Through extensive R&D testing of competitor’s kits, we know that the cheaper systems produce less light output, incorrect beam patterns, slower start up, with increased glare & compatibility issues.

Warranty & Support

Due to the high quality components used in both the bulbs & ballasts, we have such confidence in the product, that we can proudly offer a no-quibble 2 year warranty. To make fitting the kit even easier, we’ve written our own comprehensive instruction manual, as well as a handy fault-finding guide. Should you ever encounter any difficulties, we’re at the end of a phone for specialised technical support & service.

Even More Light, with Crystalite

To get the very best from your new headlights, we highly recommend the Crystalite ‘Rapid Headlight Restoration’ Kit from Twenty20. The kit comes with everything you’ll need for crystal clear clarity, to get the very best from your bulbs - as a bulb can only perform to it’s full potential when it’s behind a clear lens. Over time sunlight will remove the UV protection on your headlights and this can lead them to be dull, yellowed and oxidised. Crystalite not only brings them back to life looking like new, but will replace that all important UV protection. With no creams, polish, tape or drills, it’s incredibly easy to apply and anyone can do it, in minutes.

This is the second Stealth kit I have purchased, the first went on a Smart For two I use to travel to the airport in. Country lanes often early in the morning. The light set up is modern but the bulbs were very dim. I fitted the 35W kit pure white and it was a different world just like driving in daylight compared to squinting in the dark. So impressed I have just bought a 55W blue tint set for my TVR Griffith 500 which has milky lenses and the power of a glow worm. Again the transition is incredible even in a 5 1/4" headlight with poor lenses the mass of light simply overpowers all the negatives.

Advantages: Very well made, when you receive the kit and open the box you know you are looking at a well made quality product not some cheap import from Asia. Fitting couldn't be more simple even though it is quite a bulky set up. I got the wires wrong on the Smart car so had a look at the instructions, swapped them round and they worked perfectly. Same with the TVR managed to rivet the unit to the wheel arch and cable tie everything else neatly in place. Delivery service was faster than promised and an invoice came through the post.

Disadvantages: I cant see any, some may think the kits are expensive but for what you get they are not, they represent value for money and seeing where you are going is more important than buying fancy parts for your car.
